To the set of textiles that are at the service of the Church the expression "vestments" is used, designating, thus, the liturgical garments and all the garments used by the celebrant in the cult. Each vestments performs its function, differentiating itself according to the hierarchy of the members of the clergy and with the liturgical celebrations.

In their origin, they were modest pieces that throughout the centuries were adapted to the taste of each epoch. The allusion to the use of specific clothing is referred to in two moments: the use of liturgical clothing in the Old Testament (Jewish tradition) and the evocation of the apostles' clothing (apostolic tradition). However, the use of specific clothing for liturgical celebrations was not a common feature in the early centuries of the Church, so that each place and tradition had its own custom in liturgical clothing.

During medieval times, the choice of the type of cloth that should have been destined for the sacred vestments was not yet fixed, although, little by little, it was noticed by some varieties of cloth, according to the type of clothing. It was only after the Council of Trent that the qualities of cloths with which the liturgical garments were to be made were to be definitively regulated, for example, the chasubles were obliged to be silk, although Francisco Cristóvão affirmed that Mumadona in 959 refers to the existence of chasubles Of linen. Wool, linen, cotton, silk and precious metal yarns are the usual elements in the fabrics of the sacred paraphernalia during that time.

As a rule, liturgical garments are made up of ensembles, such as chasubles, dalmatics, stoles, handles and coverings made with the same fabric and the same composition scheme. Sometimes the altar fronts match the priest's garments, as well as the body bags, the chalice veil, and the veil of the shoulders.

It is evident in the Vestments' Core the set of vestments dated between the seventeenth century and the twentieth century. However, of all the paramentaria, the cover of asperges is the vest that causes an enormous visual impact, considering that it holds greater importance in all the liturgical ceremonial.
